X9317WS8I-2.7T2

Digital Potentiometers Overview

The X9317WS8I-2.7T2 is a single-channel digital potentiometer from the Renesas XDCP series, featuring a 10 kOhm resistance value and 100 taps. It utilizes a non-volatile memory architecture to retain wiper settings without power. The device operates on a serial interface (U/D, INC, CS) and supports supply voltages ranging from 2.7 V to 5.5 V. Packaged in an 8-SOIC format, it is designed for surface-mount installation with a linear taper configuration.

Digital Potentiometers Feature Summary

• Non-volatile storage maintains wiper position after power cycles
• Serial control interface requiring only three pins (U/D, INC, CS)
• Wide operating voltage range from 2.7 V to 5.5 V
• 100-tap resolution with 10 kOhm total resistance

Digital Potentiometers Applications

• Audio volume control circuits
• Gain adjustment in instrumentation amplifiers
• Voltage reference trimming
• Calibration of sensor signal paths

Digital Potentiometers Procurement Notes

Verify the specific suffix 'T2' against official Renesas documentation, as standard tape-and-reel packaging is typically designated by 'T1'. Confirm current availability status, as many variants in this family are marked as obsolete or end-of-life. Ensure RoHS compliance details match the specific manufacturing lot requirements for your application.

Digital Potentiometers Selection Notes

Select this component when non-volatile retention is required to eliminate initialization delays at startup. The 10 kOhm resistance value suits moderate current applications. Verify that the 8-SOIC package dimensions fit the PCB footprint constraints. Ensure the control logic levels are compatible with the 2.7 V minimum supply voltage if operating in low-power systems.

Digital Potentiometers Part Context

This part belongs to the X9317 family of CMOS digital potentiometers. It shares architectural similarities with other members like the X9317WS8IZ but differs in voltage range and packaging options. The 'I' suffix typically denotes industrial temperature range operation (-40°C to +85°C).

Digital Potentiometers Replacement Considerations

Direct substitutes include X9317WS8IZ-2.7T1 for tape-and-reel versions. For pin-compatible alternatives with similar specifications, consider the X9317WM8IZ or X9317UV8IZ series, ensuring voltage and resistance values align with design requirements.
